SAFETY GROUND
In addition to ensuring safety in the event of an electrical short-circuit, the safety ground also prevents timer problems caused by electrical power line noise. THIS PIN
MUST BE CONNECTED TO SFAETY GROUND! The safety ground is the facility ground or earth ground. Commonly, a green wire is connected to a cold water pipe to
provide the safety or earth ground. This ground must be solid and electrically conductive. Remove any paint or coating that could prevent conductivity.
